The support assembly 100 includes a mounting plate 101, a housing 102, a door panel 103, and an electrical main body 104. The housing 102 is fixed to the excavator via the mounting plate 101 and is welded to the mounting plate 101. The electrical main body 104 is fixed inside the housing 102 and is an electrical control element for controlling various electrical components on the excavator. The door panel 103 is rotatably connected to the housing 102. It also includes an air outlet 105, an air inlet 106, and a filter assembly 200. The air outlet 105 and the air inlet 106 are located on both sides of the housing 102, and external air enters the housing 102 through the air inlet 106. Air inside housing 102 is discharged through air outlet 105. As air is discharged from housing 102, it carries away the heat generated by the operation of the electrical main unit 104 within housing 102. The filter assembly 200 includes a cooling fan 201, a filter plate 202, a fixing plate 203, a storage cavity 204, a partition 205, a cleaning plate 206, an air inlet 208, a baffle 209, and a scraper 212. The fixing plate 203 is fixed inside housing 102, forming a storage cavity 204 between the fixing plate 203 and housing 102. External air enters housing 102 through the storage cavity 204. The filter plate 202 is placed inside the storage cavity 204 to intercept dust entering the storage cavity 204. The cooling fan 201 is fixed to the fixing plate 201. On the 03, external air is driven by the cooling fan 201 to enter the housing 102 through the storage cavity 204; the partition 205 is fixed in the storage cavity 204 and is used to fix the cleaning plate 206. The cleaning plate 206 is rotatably connected to the partition 205 and can clean the dust attached to the filter plate 202. The partition 205 has an air inlet 208. After the external air enters the storage cavity 204 driven by the cooling fan 201, the air passes through the filter plate 202, and then through the air inlet 208 on the partition 205 and enters the housing 102. The cleaning plate 206 is located on the side facing the filter plate 202. The filter plate 202 is slidably connected to the housing 102. 02. First, water is injected into the storage cavity 204. The filter plate 202 can absorb the water. When cleaning the filter plate 202, the filter plate 202 is slid up and down in the storage cavity 204, so that the filter plate 202 and the cleaning plate 206 move relative to each other. During the movement of the filter plate 202, the cleaning plate 206 squeezes the filter plate 202 and cleans the dust off the filter plate 202. The filter plate 202 is located between the partition 205 and the box 102. The cleaning plate 206 is rotatably connected to the side wall of the box 102 adjacent to the filter plate 202. The cleaning plate 206 contacts both sides of the filter plate 202. When cleaning the filter plate 202, it is cleaned from both sides at the same time. The cleaning plate 206 is located in the storage cavity 204.A rectangular cavity is formed inside the side wall of the housing 102. A baffle 209 is slidably connected inside the rectangular cavity. When cleaning the filter plate 202, water is injected into the storage cavity 204. At this time, the cooling fan 201 stops running, and the air inlet 106 is blocked by the baffle 209, so that the water remains in the storage cavity 204. The scraper 212 is a rectangular frame. A rectangular opening is formed at the top of the housing 102 for the filter plate 202 to pass through. The scraper 212 is fixed to the rectangular opening. When cleaning the filter plate 202, the scraper 212 can squeeze the filter plate 202. After the filter plate 202 is cleaned, the residual water inside the filter plate 202 is squeezed out, and then the water in the storage cavity 204 is discharged through the air inlet 106.

[0043] Preferably, a baffle plate 207 is fixed inside the storage cavity 204. The baffle plate 207 is located between the fixed plate 203 and the partition plate 205. When cleaning the filter plate 202, the water injected into the storage cavity 204 is always below the baffle plate 207. When the water level in the storage cavity 204 is close to the baffle plate 207, the water injection into the storage cavity 204 is stopped. The baffle plate 207 can prevent water in the storage cavity 204 from entering the box body 102.

[0044] Preferably, the barrier plate 207 is a rectangular plate.

[0045] Preferably, the fixing plate 203 is fixed to the inner side wall of the box 102, and a gap is left between the top of the fixing plate 203 and the box 102; the cooling fan 201 is fixed in the gap between the fixing plate 203 and the box 102, and the external air passes through the gap between the fixing plate 203 and the box 102 and enters the box 102 under the drive of the cooling fan 201.

[0046] Preferably, the fixing plate 203 is an L-shaped plate, and the fixing plate 203 and the side wall of the box 102 form a storage cavity 204 for placing the filter plate 202. The fixing plate 203 and the side wall of the box 102 are welded and fixed so that the storage cavity 204 can hold a certain amount of water.

[0047] Preferably, a water supply pipe 210 is fixed to the side wall of the housing 102, and the water supply pipe 210 is connected to the storage cavity 204; when cleaning the filter plate 202, water is injected into the storage cavity 204 through the water supply pipe 210 and water in the storage cavity 204 is discharged.

[0048] Preferably, both the air outlet 105 and the air inlet 106 are multiple rectangular openings.

[0049] Preferably, the baffle 209 is a rectangular rubber sheet.

[0050] Preferably, the baffle 209 has a rectangular opening with the same shape as the air inlet 106. When cleaning the filter plate 202, the rectangular opening on the baffle 209 and the air inlet 106 are staggered. After water is injected into the storage cavity 204, the baffle 209 and the box 102 are fitted together under the action of water pressure, thereby preventing water in the storage cavity 204 from leaking out from the gap between the baffle 209 and the box 102. After cleaning, the rectangular opening on the baffle 209 is aligned with the air inlet 106, allowing external air to enter the box 102. A rectangular opening is provided on the top of the box 102, and the baffle 209 is slidably connected to the side wall of the box 102 through the rectangular opening. The position of the rectangular opening can be adjusted by sliding the baffle 209 up and down in the side wall of the box 102.

[0051] Preferably, the filter plate 202 is a rectangular sponge plate. The filter plate 202 can adsorb dust in the air. When cleaning, the filter plate 202 is soaked in water, and the dust inside the filter plate 202 can be squeezed out by squeezing the filter plate 202.

[0052] Preferably, a handle 211 is fixed to the top of the filter plate 202. By pulling the handle 211, the filter plate 202 slides in the storage cavity 204. The thickness of the filter plate 202 is greater than the width of the rectangular opening on the scraper 212. The rectangular opening on the scraper 212 is located in the storage cavity 204. When the filter plate 202 is pulled upward, the scraper 212 squeezes the filter plate 202, squeezing out the water absorbed in the filter plate 202. The squeezed water will re-enter the storage cavity 204. The partition 205 can intercept the water squeezed out by the filter plate 202 in the cavity between the partition 205 and the box 102, thereby preventing the water squeezed out by the filter plate 202 from flowing into the box 102.

[0053] Preferably, the air inlet 208 on the partition 205 is located between the cleaning plates 206, and the cleaning plates 206 can prevent water squeezed out from the filter plate 202 from entering the air inlet 208.

[0054] Preferably, the cleaning plate 206 is a rectangular plate.

[0055] Preferably, a filter screen is fixed to the air outlet on the side wall of the housing 102. When the filter plate 202 needs to be dried, the cooling fan 201 reverses, allowing outside air to enter the housing 102 from the air outlet. As it passes through the filter plate 202, it carries away the moisture inside the filter plate 202 and discharges it from the air inlet 106 into the housing 102.

[0056] Preferably, the cooling fan 201 is driven by a motor. The cooling fan 201 can reverse to blow the air inside the housing 102 out through the air inlet 106, dry the cleaned filter plate 202, and carry out the heat generated by the electrical main body 104 inside the housing 102. A filter screen is fixed at the air outlet 105. At this time, the outside air enters the housing 102 through the air outlet 105.

[0057] In practical use, a control box for a mining excavator according to an embodiment of this application is as follows:

[0058] When cleaning the filter plate 202, first slide the baffle 209 to the closed position, and inject water into the storage chamber 204 through the water supply pipe 210. When there is enough water in the storage chamber 204, the filter plate 202 absorbs enough water. By pulling the handle 211, the filter plate 202 slides up and down in the storage chamber 204. The filter plate 202 comes into contact with the cleaning plate 206. When the filter plate 202 slides, the cleaning plate 206 squeezes the filter plate 202, cleaning the dust inside the filter plate 202. When the filter plate 202 is pulled, the scraper 212 can remove the dust from the filter plate 202. The residual moisture inside the filter plate 202 is squeezed out, thereby cleaning the dust remaining inside the filter plate 202. After cleaning, the water in the storage chamber 204 is drained through the water pipe 210. Then, the baffle 209 is slid to the open state of the air inlet 106. At this time, the cooling fan 201 continues to operate. When the filter plate 202 needs to be dried, the cooling fan 201 reverses, allowing outside air to enter the housing 102 through the air outlet 105 and then exit the housing 102 through the air outlet 105. When the air passes through the filter screen, it carries away the residual moisture in the filter plate 202, allowing the filter plate 202 to dry.

[0059] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. For those skilled in the art, various modifications and variations are possible with this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
